To all whom it may concern: which a and a designate two sets of warps Be it known that we, WILLIAM BECK, of for the outermost reinforcing layer or ply; 1) Lawrence, in the county of Essex, and JAMES and b, two sets of warps for the wider rein- F.

It will be seen that the fillinging the course of the filling or weft threads in thread f is laid under the set of stitching- 9o diiferentpicks. Fig. 5 is a fragmentary lonwarps. For the next pick the sheds are made 45 gitudi'nal sectional illustration of the fabric. up as follows, (see Figs. 2 and 2%) The upy In making the fabric shown in the drawper side of the upper shed comprises both ings we employ ten sets of warp-threads, of sets of warps a and c belonging to the outer ply and one set of warps Z) of the inner ply. The lower side of the upper shed and upper side of the lower shed comprise the otherset of warps l) of the inner ply, the extra warps bl, and one set of warps d of the upper side of themain tube. The lower side of thelower shed comprises the tie-threads or stitchingwarps c, the other set of warps (Z of the upper side of the main tube, and the two sets of warps e and e belonging to the lower side of the main tube. The filling-thread f will then be laid in the upper side of the main tube above the tie-threads or stitching-warps c (from 2 to 2 in Fig. 2*) while the fillingthread f is being laid in the inner reinforcing-ply from one edge of the same beyond the corresponding edge of the outer ply as far as the other edge of the latter, but not to the corresponding edge of the inner ply, (from 3 to 3, Fig. 2".) It will be noted in this connection that the two sets of warps Z) and I), while of the same width, are offset from each other laterally, so that they overlap only throughout the width of the outer ply, and the warps lying beyond work in conjunction with the two groups of extra warps I), respectively. (See Figs. 1 to P.) For the next pick the upper side of the upper shed comprises only the set of warps a of the outer ply, and the lower side of the lower shed comprises only the warps e of the lower side of the main tube, so that all the other warps are between the two sheds. Hence the filling-threadf is laid in the lower side of the main tube (from 2 to 2", Fig. 3 and theifilling-thread f is laid simply in the outer reinforcing-ply, (from 3 to 3 Fig. 3.) It will be noted that the tie-threads have moved up into the top of the lower shed, and it may be added that they remain in this intermediate position during the next pick also. For this next pick the top side of the upper shed comprises both sets of warps a and a of the outer ply and the set of warps b of the in ner reinforcing-ply. Theintermediate warps comprise the other set I) belonging to the said inner ply, the extra warps b, the stitchingwarps c, and the set of warps d of the upper side of the main tube. The lower side of the lower shed comprises the other set of warps d belonging to said upper side of the main tube and the two sets of warps of the lower side of the latter. It follows that the fillingthreadf will be laid in the upper side of the main tube (from 2 to 2", Fig. 4*) while the filling-thread f is being laid in the inner reinforcing-ply from one edge of the outer ply to the far edge of the inner ply, (3 to 3", Fig. #2) For the next pick the sheds are formed as first described, the stitching-warps and the extra warps I) being carried into the upper side of the upper shed. This, it will be seen, occurs at every fourth pick, the said extra warps remaining in the lower side of the top shed and upper side of the bottom shed during the three intervening picks, whereas the stitching-warps go down into the lower side of the bottom shed for the first succeeding pick and then remain in the upper side of said shed during the other two picks of the three referred to as intervening.
It will be seen that by pursuing the method above described a continuously-woven main tube will be produced by the filling-threadf and the warps dd and e e, and simultaneously two reinforcing-plies,tubularly continuous and comprising the warps a and at, those of the warps b and b which are superposed, and the filling-thread f. At the same time extensions of the inner ply are woven composed of the rest of the warps Z) Z) and the extra warps l) and the filling-thread f. Furthermore, both reinforcing-plies are tied together throughout the width of the outer ply by the stitching-warps, which also unite the plies to the upper side of the main tube, including the lateral extensions of the inner ply.
It will be seen that the object primarily stated is thoroughly accomplished by the con struction of fabric herein specifically described. However, it is to be understood that this construction is susceptible of modifications within the scope of the invention.
The method herein described is claimed in a separate application, Serial No. 555, filed by us January 6, 1900.
Having thus explained the nature of the invention and described a Way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is 1. Fabric hose for tires, the same comprising a continuously-woven tube, and a plurality of tubularly continuous reinforcing-plies overlying the tread portion of said tube and stitched together and to the tube.
2. Fabric hose for tires, the same comprising a continuously-woven tube, and a plurality of tubularly continuous reinforcingplies overlying the tread portion of said tube, and single-ply lateral extensions fromthe junctions of said reinforcing-plies, the latter being stitched together and to the main tube together with the lateral extensions.
3. Fabric hose for tires, the same comprising a continuously-woven tube, and a plurality of tubularly continuous reinforcing-plies overlying the tread portion of said tube, together with stitching warps or tie-threads uniting the reinforcing-plies together and to the tube.
4. Fabric hose for tires, the same comprising a continuously-woven foundation-tube, a tread-reinforce double' ply at the middle and single ply at the sides, each ply having its own warps but the filling thread or weft of the entire reinforce being common to all the plies and extending as follows: from one edge of the single-ply portion of the reinforce to the double-ply portion and then through ner'ply and the single-ply part of the reinr.
